I have been using this for 5 days and am very pleased with it. 
It took a little time to install the bracket to the wall so that there is no risk of the oven tilting. The ceramic top is easy to clean after wiping Cerama Bryte on it first (that was recommended). The oven functions well, and my veg and potatoes were evenly roasted. I will have to buy an air fryer tray to take better advantage of the convection function.
There is a gap just under the oven functions with does get dirty, but this allows venting from the oven. I'm just wondering how I will clean this in the future!
